rlVIIElTIIOJD OF AND APPARATUS FO'R COMPOUND LINYING CAN ENDS.

Application filed February 24, 1920. Seriali No. 360,524.

To all who-fmy it may concern:

Be it knownthat-I, HARVEY L. BRYANT,

a citizen. of the United States, residing at 1556 41th Ave., Brooklyn,in the county of Kings and State of New York, have invented certain newand useful Improvements in- Methods of and Apparatus for Compound.Lining Can Ends, of which the following is a specification.

The hereinafter described invention is more particularly designed forthe compound lining-oli theflanges of what is commonly known asirregular-shaped can ends, the construction andl operation of theinterconnected working parts of the apparatus and the method ofprocedure being such that during the continuous travel of a can end fromthe receiving to the discharge end-l ef the apparatus, the said end isturned to exposethe flange therec'ite the means for applying thecompound lining' material thereon; the object of the invent-ionbeing toyfacilitate the compound lining ot the flange of irregular shaped canends and to avoid the transfer ot the unlined can ends from theconveying means onto transfer means for placing the said end within thesphere of'. the compound liner applying mechanism, thereby dispensingwith the transfer of the ends, and; by so` doing simplifying theconstruction and operation of the apparatus, producing more eicientmeans for the com poundi lining of the flange oli the irregular shapedcan ends, and materiallyincreasing the output ofa compound liningapparatus.

The apparatus disclosed herein for carryingv out the invention comprisesmeans for conveying can ends continuously iny a straight line asdistinguished from machines of a circular or straight line intermittenttype. In` this invention the can ends` are notretained during the periodthe lining material lis being applied to their flanges. -As far as Iamaware all previous machines for applying lining material to the flangesel' can ends through the medium ci' valve controlled nozzles, rotate thecan ends with the flange to be lined, describing a path directlyunder afixed nozzle. In order to do this the can ends must have intermittentmovement through the machine, this necessarily restricts the output,because suflicienttime must be allowed each period of rest to give thelining material time-toll'o-w from the nozzle onto the flange of therotating can end. This kind of' operation is particularly slow with thelrectangular ends, for the lining of which this invention is particularlyadapted. Practically all rectangular or irregular shaped can ends haverounded corners, andwhile this is a straight line machine I haveprovided means through a slight swinging movement given to the liningnozzlesso the rounded corners are lined without in any manner retardingthe continuous rforward movement of the can ends through the machine.

To comprehend the invention, reference should be had to the accompanyingsheets of drawings, wherein is illustrated a preferred embodiment of anapparatus for the practical carrying out of the invention, and wherein,

Fig. l is a plan view of the apparatus, illustrating the path of travelof can ends therethrough, the said ends being shown as unlined, partlylined, and wholly lined.

Fig. T is a detailed sectional view taken on line 'T-7 of Fig. 2 of thevdrawings and viewed in the direction of the arrows, illustrating themeans for restoring the can end or cover carrier blocks to normalposition after the lined can end has been discharged therefrom.

Fig. 8 is an enlarged detail view illustrating one of the can' end orcover carrier blocks and its connection with the endless conveyer.

In its preferred embodiment the operative apparatus for the carrying outof the invention comprises a suitable supporting frame, in the presentcase composed of angle members 1, 2, '3 and the transversely disposedconnecting members al.. Longitudinally of the frame and intermediate theside members 2 thereof are dis nosed the spaced members 5, which areheld a slight distance above the frame of the apparatus by means of thespacing blocks 5, Figs. 3 and d of the drawings, and they are bolted orunited to the end members 3 and the transversely disposed members 1 bymeans of suitable bolts 5a (Fig. 1) passing through the spaeing blocks.Intermediate of the members 5 is located a longitudinally disposedchanneled member 6, which provides a longitudinal guide-way 6 in whichtravels the upper run `of an endless travelling. conveyer or carrier T,which, in the present case, is illus- `trated as comprising an endlesschain.

The endless carrier 7 is provided with a series of upwardly projectingspaced lugs or flights 8, to which are secured the can end or coversupports, carriers o r carrier blocks 9. The circular head extension 8of each lug or flight 8 projects through a central aperture in thecarrier blocks Sl, each block being rotatably held to its flight 8 bymeans of a securing screw 10, which holds a washer 11 within a centralcounter-sunk portion in the upper face of the said cover block f), Fig.el; of the drawings, Each' carlrier block Si is free to rotate or turnon 'the circular extension of theslugs of the endless .carrier when thesaid blocks are acted on by the means for shifting or turning theposition thereof as the blocks areY carried successively past thecompound liner stations of the apparatus hereinafter referred to. Theendless carrier 7 works over the end sprockets 11 and 12 of theapparatus, Fig. 2 ofthe drawings, the sprocket .12 being driven by anysuitable outside source of the.

power applied to the belt pulley 13, which pulley is mounted on theshaft 141 to which the 'sprocket 12 is attached; the shaft 1-l andequally so, the shaft 1a for the sprocket 11'- working in suitablebearings of the apparatus. To maintain the tension of the endlessycarrier T or prevent loose play thereof, there is provided anidlersprocket;1-5which engages with the underrun of the said endless carrier,Fig. 2 of the drawings, the said idler sprocket 15 being secured to orcarried at the inner or free end of a ldownwardlyextended arm 1G,pivoted at its upper end portion to the frame structure of theapparatus.

At any suitable point relative to the apparatus is provided a can end orcover holding table 17, Figs. 1 and 2 of the drawings, from which leadsa downwardly inclined feed chute 18, which at its lower vendhas'attached thereto an outwardly projecting spring-clip 19; the saidclip-.being attached to a centrally disposed retaining bar 2O lo-lcatedwithin the sphere of the feed chute 18, and which retainingbar preventsthe' an covers or ends 21 from becoming displaced as the same move bygravity down the inclined feed chute 18.

Each carrier block 9 is `of a shapecorre-` spending to the panel of thecan cover-cr end 21 the liange of which is ,tol be compound lined, beingherein shown las rectan-v gular with rounded corners, which shape isV tobe varied to correspond with the shapes of can ends of other contourwhich are to,bc lined with coi'iipound, and the covers v21 as they leave'the chutev 18 rest at their forward end onto "the-two supporting blocks2 2, secured to the upper face of the longitudinal plates' 23,'-whichplates in turn are attached to the upper portion of the channeled guidemember (i for the endless carrier. Two pair of guides are utilized inthe present apparatus, the first pair 23 terminating atva point. justlbeyond the first pulp lining station'A of the apparatus, while thesecond pail of guides 23` extend fromia point just beyond the tripmechanism for thc carrierblocks and terminate at a point beyond thesecoi-idv4 compound lining station l5, Figs. 1, 5 and (3 of thedrawings. The carrier blocks ,are held a slight distance above the-Vguides g2?) and 223- and each block below its `upperA portion forengaging with the panelof the can ends or covers is provided vwith acani surface 24, shaped to the contour .or configura-v tion of the canend or cover 21, the liange of. which is to be lined, andbelow thecamsurface portion 24, thereof is formed with a square portion 25, Fig.8 of the drawings.. 'lfhe square portion 25 of the carrier blockscontacts with the inner .walls .of thc guidesand 23 duringthecourse oftravelof the carrier blocks through the apparatusv and by means of theseguides the said blocks are. held against turning movement, so long asthe said blocks are within the sphere of the said guides.

In the present apl'iaratus two pulp lining stations are provided. viz:station and station l. At each ofthe lining stationsabove the frame olthe apparatus is mounted ya plurality of holding reservoirs for thecom-'3 'lil pound linermaterial, which reservoirs are arranged .in.pairs at :each station, ybeing designated respectively by -thenumeralsand :252 and 26 and126. Each compound holding reservoir issecured to a laterally movable. U-shaped bracket 2T, mounted or Securedto the rswinging armsl 28, which said arms lare pivotally secured to thelongitudinal members 5, Figs. 3, 4 and of the drawings. `There isinterposed between the brackets 2T and the pivotal arms 28, the spacerblocks 28 said blocks at their inner ends being` downvuirdly vandinwardly bent so that the vfree ends thereof `lie in a plane slightlybelow the member 5, and tothe free ends of each block is mounted a`roller 2 which rollers work overthe cam surface 24 of the carrierblocks 9. 1t will be understoodithatt-hese rollers A'would worksimilarly on carrier blocks of other shape, corresponding with-othercan-ends to be treated. Each pair of `pivotal arms 28 are 'held inwardlypressed at their free ends by the tension of the connecting springs 30,Figs. l. 3 and 4 of the drawings, in which inwardly pressedpositionpthey are maintained until lspread apart by the pressure'of'atravelling carrier block onto the follower rolls 29, as the said blockswith a cover applied thereto are-carried past either vof the compoundlining stations. i

Each compound holding reservoir is provided with a valve-controlledoutlet 31, the escape of compound through the outlet of each lreservoirbeing controlled by acneedle valve 32P/,thestem`32 of which lvalveextends beyond its holding reservoir and is formed slightly larger than'the lneedle valve, vand at its lower end is screw-threaded to receive acoller 33 against which a spring 33 bears, said spring surrounding thestemV of the needle valve and being confined between the collar and theinner end. of afbracket 34 upwardly projecting from the 4reservoir 25.The compound` 'lining material is supplied under pressure to thecompound holding reservoirs 25, 252, 26 and 26", 'by ine-ans of the feedtubes 35, which tubes lead from any suitable source -of pressure supply,Figs. 2, 3 and et of fthe drawings.

As the rollers 29 work over the cam surface of the'ca-rrier blocks 9during the movement of the endless carrier t-hrough the apiliaratus, theU-shaped brackets 27 supporting land 'carrying the compound holdingreservoirs 25 are caused to move inwardly and outwardly with the travelof the said rollersover the cam surface 2d- Vof the carrier blocks 9,and moved the lower arm a, of aV crank lever 36 engages with ahorizontally disposed spring-held rod 37, Figs. 3 and i of the lrawingsso as to throw the upper arm 7) of said lever to raise the needle valvesto open the discharge outlet 3lV of Ithe reservoirs and permit theescape of liner com pound from within thel said 'holding reservoirs. Themoment a carrier block with a can end or cover supported thereon is bythe travel of the endless chain or carrier moved from within the sphereoi.' the Vseid rolls .29, the action of the springs draws inwardly thefree ends ofthe swinging arms 28 and carrying therewith the U-shapedbrackets 27 places the lower arm o of the crank levers 36 out ofengagement with the spring-held rods 37', when the tension of thespring` 33 gradually lowers the needle valves 32 to close the outlets 3lof the liner material holding reservoirs to cut off the escape of thematerial therefrom.

The outward movement of the rolls 29 riding over the cam surfaces of thecarrier blocks 9 is so timed that the movement beginsjust as the can endis approaching the nozzles l31. This preliminary outswing ot thereservoirs 25 and 252 and the nozzles 31 causes them to describe acurved path approximately in shape to Itl'iat of the rounded corners. ofthe approaching rectangular can ends. This action operates means thatstarts the flow of compound justas the outlets of the nozzles 3l aredirectly over the rounded corner flanc-es, so that the initialapplication of compound is-on the ycurves of the flanges, passingimmediately onto the straight side. The reverse action takes place justas the can ends pass away vfrom the nozzles 31. The rolls 29 ridinginward over the cam surfaces of the blocks 9 cause. fthe lnozzles'31 tode-` scribe' a. path similar tothe curved corners ofthe passing can endsand apply compound thereto during VKthis final swinging movement. It isnot necessary `to apply the compound over the entire curve at thefirst-station, since the action 1at' the second lining station issimilar. 1t Vis therefor only necessary Ito Vhave the 'parts andmovements so timed 'that the .lining material applied at thecornersoverlaps, on account of its fluid nature it will run together andmake acontinuous :film with the lining material applied on the straight-sides of the flanges. Fig. I3 of the ldrawings showsthe reservoirs 25and 252 in itheirnormal inoperative position with the nozzles 31 lyingwithin the path Aof the straight portion of the can flanges and in thepositionatwhich the)- begin to move outward and discharge liningmaterial around *the approaching ycurved cornersof a can end.` f

lDuring the "movement of the carrier blocks 9 throughfthe apparatus withends or covers applied vthereto for lining, the canends or covers areheld to the carrier blocks and prevented against apward movement ordisplacement by means `of 'the longitudinally disposed guard rail 38which is arranged centrally of the apparatus above the said blocks andAheld a slight distance above'the upper surface'of the covers appliedthereto.

As the lined can ends or covers 21 approach the discharge end of themachine, the same are delivered onto the spaced angle stripper bars 39,which serve as the discharge portion of the apparatus for the lined canends or covers, the said ends or covers being delivered onto the forwardend of the saidv bars as the carrier blocks approach for travel over thesprocket 12; the carrier blocks at such time passing between stripperbars 39 and the can end or cover being stripped, so to speak, from thesaid blocks, it being understood that each succeeding can end or coveras delivered onto the stripper bars gradually pushes the previouslydeposited lined ones thereover. The lined can ends as forced along orover the stripper bars 39 are held in place by the retaining rail orplate 39', which, if so desired, may constitute a continuation of theretainingr plate or rail 88.

Just beyond the pair of spaced follower rolls 29 which are situated atthe liner station A, is located a horizontally disposed trip dog 40,which is pivotally connect-ed for swinging movement to the upper face ofone of the guide plates 23, Figs. 1, 5 and 6 of the drawings. This tripdog is normally held inwardly pressed by a spring 40, so as to'cause thehooked end 41 thereof to project within the path of travel of the squareportion 25 of the carrier blocks 9 of the endless carrier 7. Vith thedog thus positioned, as a carrier block is moved beyond the liningstation A, the hooked end thereof engages the square portion of thecarrier blocks and by reason of the pulling strain exerted thereon bythe travel of the endless carrier, the carrier block with a can end orcover thereon is turned or part rotated to place its unlined end flangewall portion e for alignment with the discharge outlets of the compoundholding reservoirs 26 and 26 situated at the lining station B of theapparatus, the end flange wall portion 0l of the can end having receivedliner material from the reservoirs 25 and 252, as advanced beneath thesame with the flange walls d positioned parallel with the central guideway of the apparatus.

In the compound lining of the flange of can ends or covers, theoperation of the described apparatus is as follows The can ends 21delivered from the table 17 move down the inclined chute 18 until thesame project below the lower end thereof, at which time the can endrests on the blocks 22 and stands at an inclination to the horizontal,being held in position by the spring-clip 19. The can end at such timeoverlies the guide-way formed by the channeled guide member 6, the side'flange portion (Z of the unlined can end being parallel with thedischarge outlets of the liner compound holding` reservoir 25 and 252and the forward edge of the panel of the can end being in a planeslightly below that of the upper surface of a can carrier block of theendless carrier. As a carrier block 9 of the endless carrier isadvanced, the forward edge thereof engages with the inner surface of thepanel of the positioned can end and draws the same from oft' the chute18 and supporting blocks 22, the can end gradually lowering onto the canend carrier block. The can end thus positioned is advanced by thecontinued movement of the endless carrier toward the lining station A,where as the carrier block moves between the follower rolls 29, the saidrolls and the pivoted arms 28, together wIith the connected brackets 27are moved outwardly or spread apart, the movement of these memberscorresponding with that of the follower rolls 29, working over the camportion 24 of the rotatable carrier blocks. As the members actuated bythe movement of the first pair of follower rolls 29 over the cam portion24 of the carrier block 9 duringthe advancing movement thereof betweenthe said rolls are moved, the compound holding reservoirs move therewithto place the. discharge outlets thereof in axial alignment with theportion Z of the flange of the can end to be lined, at the same time thethrow imparted to the crank levers 36 raising or unseating the valves 32of the reservoirs to permit the escape of the liner compound therefromand the flow thereof onto the unlined portion d of the flange of the canend.

The spring-held follower rolls 29 gradually move inwardly for throwingthe crank levers 36 to close the discharge outlet of the liner materialholding` reservoirs as the carrier block 9 with its applied can endmoves from within the sphere of the said rolls. The partly lined can endis then advanced toward the lining station B, and during suoli movementthe pivotal spring-held dog 40 engaging with the square portion 25 ofthe carrier block 9 and thc pulling strain exerted thereon causes thegradual turning or part rot-ation of the carrier block 9 until theunlined portion c of the flange of the can end is placed in position foraxial alignment with the discharge outlet of the holding reservoirs 26and 26. As the turned carrier block, after moving from within the sphereof the trip dog` 40 advances between the second pair of follower rolls29 situated at the second lining station B, the said spring-heldfollower rolls 29 are forced apart or outwardly, riding at such timeover the cam portion 24 of the carrier block 9. This movement of thesaid follower rolls outwardly moves the swinging arms 28 and theU-shaped brackets 27, to place thc discharge outletsv of the reservoirs26 and 26 in axial alignmentl with the unlined portion c of the can endflange. As thus moved out- CII wardly,'the spring-held rods 37 engagewith y and force ini'vardiyT the lower 'arm t of the pivotal crank'levers 36, causing an vupward throw of the arm'b o'f's'aid leversto'raise or unseat the valves 32 of the liner compound holding`'reservoirs 26 and 26 to permit an escape of the compound therefrom andthe flowing thereof onto "the unlined portion of the 'can end :flangeduring the longitudinal advance 'through the machine of the carrierblock 9 'on which thecan end is supported. @n the carrier block withlits supported can end moving from within the sphere of the followerrolls 29, a reverse movement is imparted to the' described parts whichrare restored to 'normal position. It will loe understood that theactionrof the se'co'ndjp'air of follower rolls and their associated`parts situated at the linin'g station B is the same as the act-ion ofthe 'corresponding parts situated at the lining station A. f

As an' end carrier blo'clt with a flanged lined can end thereonapproaches the sprocket 12' at the discha'r, ,e end of the apparatus,the' under surface of 'end portions of the 'can end 'flange projectingbeyond the side wall su'rface of the carrier block is engaged byft'heinner end of the spaced strip'- per bars 39 and gradually lifted fromthe carrier block as the said block is carried over the sprocket 12 bythe travel of the endless carrier. At this time the carrier block is sopositioned that its longitudinal anis stands transverse or at rightangles to the longitudinal axis `of the' guide-way of the appa-y ratus;consequently, it is required that the same may be turned or part rotatedto its normal position, that is with its longitu` dinal axis inparallelism with the longitudinal axis of the guideway G within whichworks the endless conveye'r or carrier 7 This turning places orpositions the carrier blocks discharged of lined can ends in position toreceive an unlin'ed cany end as they move beneath the spring clip 19 atthe lower end of the feed chii'te'y I8 for the canends. In ordertoaccomplish this turning or part rotation of the can endv carrierblocks as,

moved over the sprocket l2, there is secured to one of the stripperbarsv 39 ai depending bracketflflQFigs. l, 2 and 'T of the drawings, tothe lower end of which bracket is pivoted for transverse swinging4moi'eine-nt a vertiy cally disposed trip dog 4,2, the hooked end 43 ofwhich is normally held inwardly pressed by a spring 43 to lie withinthepath of travel of the carrier blocks and to 'engage with the squareportions 2'5 thereof as the same move from beyond the sprocket l2.Thistrip dog 42 'acts in the samemannerl as the tripV dog 4&0 whichimparts initialr rota-I tion to the 'carrier blocks and serves torestore the blocks' to the position heldv prior to being actedv on bythe said trip dog Ll0.
